Abstract: As an introductory activity, I decided to focus on the muon, which I know a little about. My question was, "in what part of the detector does most of the energy of a muon get.
deposited?"

. Materials & Methods: In order to answer my question, I used the Online Graphical Root Environment (OGRE) and set the first filter to accept only muons. The data was selected form the "test beam" category. The total number of muon events was 310,000.
In order to analyze the results, I plotted a 3x3 graph of the total energy of all of my muon events, the amount of energy deposited in the e-cal, and finally the amount of energy deposited in the h-cal.
Results: Below, are the resulting graphs that were generated using OGRE.
The red graph indicates the total energy of the muon events, the white graph indicates the e-cal events, and the blue represent the h-cal events.
Once I noticed that the majority of the events were depositing 0 GeV of energy in either calorimeter, I generated a E vs. H graph as seen below. Again, the majority of the events are centered at or near 0 GeV of energy.
Discussion & Conclusion: What I had expected to see was a large amount of energy deposited in the E-cal.
Much to my surprise, there was relatively little energy deposited in either the e-cal or the h-cal. As you can see, the majority of the events that were recorded in both calorimeters are centered on 0 energy.
